63172 Spinal cyst drainage Medicare reimbursement rates in Rhode Island

A neurosurgeon uses a cervical laminectomy to reach and drain a spinal cord cyst, such as a syrinx associated with syringomyelia. The service is generally performed in a hospital operating room for a patient whose imaging and symptoms support operative treatment; the surgeon documents the cyst, its cervical location, and the drainage procedure performed.

Select this code based on the operative service and cervical site, not simply the diagnosis of syringomyelia. The operative report should identify the level and explain the cyst drainage; the laminectomy used to gain access is part of the procedure. Medicare assigns a 90-day global period, which includes the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Assistant-at-surgery payment may be allowed; co-surgeon payment requires supporting documentation, and team surgery is not permitted. Modifier 50 is inappropriate for this procedure.
